"Walter and Glen at Protect Your Home Group with ADT are the best people to talk to in terms of security alarm. Being a locksmith myself I know how important it is to deal with the right people. I referred a lot of customers to them and so far they are happy with their service. I myself got one for my house. Thank you for a consistent service and great deal."

Locksmiths FAQs, answered by experts

Yes, as long as it’s thick enough for the deadbolt. Most interior hollow core doors are at least 1 1/2-inches thick, which is usually the minimum requirement for a deadbolt. You’ll want to find the lock block first before installing. Also, most hollow doors require additional reinforcement for locks, such as a reinforcement plate or plywood block.

Always consider security a top priority in your home. Perform a safety inspection of your home. Look for broken locks and rusty deadbolts, and take an inventory of who has access to your keys.

Consider the locks on your shed, safe, and other household items. Professional locksmiths can help you determine the best safety and security options for your home and feel at ease.

When a locksmith comes to your home, ensure your safety by having the locksmith show identification and provide an itemized invoice that you can reference later.

Rekeying should be done when employees leave or keys are lost, while replacement may be necessary for outdated or damaged locks.

The cost-effectiveness of fixing or replacing a door lock depends on the severity of the issue. Repairing a minor problem, such as loose screws or a need for lubrication, is usually cheaper than replacing the entire lock. However, replacing the lock if it is severely damaged, outdated, or lacks security features may be a better long-term investment. New locks often have improved security features, enhancing your property's safety.

In general, keyless door locks are considered safe, and their security depends on the type and quality of the lock. They cannot be picked like a traditional lock and often include added features like biometric access, PIN codes, and smartphone connectivity, which can make them more secure. However, they are not without risks. Potential vulnerabilities include hacking for Wi-Fi-connected models, battery failure, power outages, and technical malfunctions. To maximize security, it is important to choose a reliable brand, stay on top of software updates, and perform regular maintenance. While the risks are different, keyless locks are not considered more dangerous than traditional locks.
